The Disruption of the Sagittarius Dwarf Galaxy [PDF]

The Astrophysical Journal, 1995
Numerical simulations of dwarf spheroidal galaxies undergoing several close encounters with the Milky Way are described. By comparing our models to observed properties of the recently discovered dwarf galaxy in Sagittarius (Sgr), we discuss implications of our results for the formation and evolution of the Milky Way system.

Dwarf Galaxies in Voids: Dark Matter Halos and Gas Cooling

Advances in Astronomy, 2010
Galaxy surveys have shown that luminous galaxies are mainly distributed in large filaments and galaxy clusters. The remaining large volumes are virtually devoid of luminous galaxies.

Mapping Corporate Investments Between China and Europe in an Era of Geoeconomic Competition

JCMS: Journal of Common Market Studies, Volume 63, Issue 3, Page 932-963, May 2025.
Abstract The consolidation of geoeconomic competition puts core aspects of global economic interdependence, such as the mutual China‐EU investment relationship, under increased pressure. Headlines about ‘derisking’, ‘decoupling’ or ‘deglobalization’ dominate current debates but tend to be overly simplistic.

Dark matter constraints from a joint analysis of dwarf Spheroidal galaxy observations with VERITAS [PDF]

, 2017
We present constraints on the annihilation cross section of weakly interacting massive particles dark matter based on the joint statistical analysis of four dwarf galaxies with VERITAS.

The G-dwarf problem in the Galaxy [PDF]

New Astronomy, 2008
The empirical differential metallicity distribution (EDMD) is deduced for (i) local thick disk stars; (ii) likely metal-weak thick disk stars; (iii) chemically selected local G dwarfs, with the corrections performed in order to take into account the stellar scale height; in addition to previous results related to (iv) solar neighbourhood halo subdwarfs;

The Canis Major Dwarf Galaxy [PDF]

Publications of the Astronomical Society of Australia, 2004
AbstractRecent observational evidence suggests that the Sagittarius dwarf galaxy represents the only major ongoing accretion event in the Galactic halo, accounting for the majority of stellar debris identified there. This paper summarises the recent discovery of another potential Milky Way accretion event, the Canis Major dwarf galaxy.

GCN5‐related histone acetyltransferase HOOKLESS2 regulates fungal resistance and growth in tomato

New Phytologist, Volume 246, Issue 3, Page 1217-1235, May 2025.
Summary The functions of histone acetyltransferases (HATs) in the genetic control of crop traits and the underlying mechanisms are poorly understood. We studied the function of tomato HOOKLESS2 (SlHLS2), a member of the GCN5 family of HATs, through genetic, molecular and genomic approaches. Tomato hls2 mutants generated through CRISPR‐cas9 gene editing

In Pursuit of the Least Luminous Galaxies

Advances in Astronomy, 2010
The dwarf galaxy companions to the Milky Way are unique cosmological laboratories. With luminosities as low as 10−7LMW, they inhabit the lowest mass dark matter halos known to host stars and are presently the most direct tracers of the distribution, mass

Verification of the Fusarium‐Increasing Properties of the Dominant Dwarfing Gene Ddw1 in triticale (×Triticosecale)

Plant Breeding, Volume 144, Issue 2, Page 151-158, April 2025.
ABSTRACT Dwarfing genes that are considerably reducing plant height are used in many cereals. In triticale, the rye‐derived dominant dwarfing gene Ddw1 was introgressed in commercial varieties. It has already been shown that this gene increases Fusarium head blight (FHB) susceptibility in one segregating population.

Single‐Cell Hi‐C Technologies and Computational Data Analysis

Advanced Science, Volume 12, Issue 9, March 6, 2025.
This review provides a detailed examination of scHi‐C technologies, offering quantitative evaluations of 13 protocols. It addresses computational challenges arising from data sparsity and presents systematic insights into data analysis methods, including clustering, TAD calling and 3D reconstruction.
